I have spatio-temporal albedo (roughly, the 'reflectivity' of earth's surface) dataset, from NASA's MODIS satellite, for a 130 square kilometer area. The dataset contains raster files in the NetCDF ...

This is my first time attempting to build a linear regression model and I am not sure what to do next given the results I have.
I have a data set with 24 predictors and 1 response and there are 999 ...

I would like to run a nested ANOVA to test three random effects (secteur, loc nested in secteur, site nested in loc) on the variable A. The design is unbalanced so I used lmer instead of aov. However, ...

I was looking at the mtcars dataset and explore the relationship between MPG and the transmission modes (auto/manual). I choose to use the following linear models with the regressors specified in the ...

While I am reasonably comfortable with performing and interpreting the output from logistic regression using glm in R, I had a question about the mechanics of the calculation to better understand what ...

In Hothorn et al, the test statistic is specified as
$$ T_j(L_n, w) = vec(\sum w_i g_j(X_{ji}) h(Y_i, (Y_1,...,Y_n)^T))$$
What is the exact form of this test statistic with a continuous response and ...

Non-specific question: There is an action that can be performed that has multiple outcomes. Each outcome has a different probably, p, of occurring. How many times, n, do I need to do the action before ...

My data frame has a 10 columns and 100,000 rows, each row is an observation and the columns are data pertaining to each observation. One of the columns has the date of an observation in the Julian day ...

I have a bunch of data that I fit a linear regression to, and now I need to find the variance of my slope. Is there an analytical way to get this?
If an example is necessary, consider this my data in ...

How can I code in R to solve for $p$ in $370=(1/p)(1/[1-(1-p)^L]),\ L=1,2,3,...$ and get the positive values of $p$ at different values of $L$ even when $p$ is at the right hand side of the equation. ...

I am importing data from an Excel file that contains 15 sheets. Each sheets represent a year in which there are observations on the same variables.
Here is what I would like to do (elgantly) from R: ...

I currently have timeseries data (of gold prices) and I am trying to use a simple smoothing forecast to estimate gold prices for the next 12 months.
I am not sure what function to use to accomplish ...

I have a need to do realtime predictions for individual rows of data based on a previously computed randomForest algorithm. How can I run the "predict" command without recomputing "fit" on the entire ...

I'm trying to combine some spatial data with a csv data frame then produce a visualisation of some features of the result using ggplot2. When I combine the data and then try to fortify the result so ...

I’m running a logit mixed-effects model on binary data with a 2x2 within-subjects design, with subjects and items as crossed random effects, and the two independent variables deviation-contrast coded.
...

I have a data set in graph format representing semantic connection between terms. The data set is divided into clusters, each with several labels (not unique, or mutually exclusive, no set number of ...
